Reasons for high hydraulic oil temperature of small excavator
Posted: Oct 24th, '24, 21:41
Small excavator are mainly used in the peak period of infrastructure construction in urban construction, energy water conservancy, road transportation and other aspects, and are widely used because of their small and flexible size and ease of transition. However, when the small excavator is used, there will be small episodes due to various factors, and the next is mainly to look at the problem of high hydraulic oil temperature of the small excavator , in fact, the main reason is that the heat is generated too fast, the heat dissipation is too slow, and the two are relatively uneven.
1. The internal blockage of the hydraulic oil radiator or the appearance of the radiator is too dirty, affecting the heat dissipation effect (that is, the radiator can not work).
2. The hydraulic oil tank lacks hydraulic oil or hydraulic oil is too dirty, and the hydraulic filter element is blocked, resulting in too high temperature (if it is not maintained for a long time, the quality of hydraulic oil will decline, the circulation performance will deteriorate, and too much heat energy will be generated).
3. Excessive leakage of hydraulic oil in the hydraulic system leads to excessive leakage of hydraulic oil, and the wear gap of the hydraulic parts of the valve core is too large, resulting in a large amount of heat resulting in high temperature;
4. The oil return check valve is damaged (the spring is damaged or the valve is stuck), resulting in no resistance to oil return or direct oil return through the radiator;
5. False positives due to circuit system failure, sensor or circuit problems;
6. Hydraulic pump internal leakage is too much, the working device is slow, resulting in high temperature;
7. The engine power is insufficient and the hydraulic pump does not match, the hydraulic pump oil supply is insufficient to increase the hydraulic system load, increase the resistance of the working device, and form high temperature;
8. For large and small excavator , the hydraulic system has a separate hydraulic fan motor, hydraulic fan pump and hydraulic fan solenoid valve. Damage to these three components will result in excessive hydraulic temperature.
